While we can't meet you in person until the health crisis ends, our volunteers are still active and available to assist you online.
We are currently offering virtual advice clinics, presentations and workshops via Zoom. Here are just a few of the many presentations we offer:
  • Houseplants: Our Constant Garden
  • Landscaping with Trees and Large Shrubs
  • Putting the Garden to Bed

Have a garden question? Visit our Ask a Master Gardener page.
We'll update this notice if things change. Meanwhile, stay safe, and happy gardening.

Kudos to LEAF, OPG's Regional Biodiversity Program, Regional Municipality of York, City of Richmond Hill and other municipalities in York and Durham. They will plant 6,000 native trees / shrubs on public lands over the next 3 years!!
